Abstract To address the poor oil–water separation efficiency and bactericidal properties of existing membranes for treatment industrial oily wastewater discharge, this study designed an in-and-out coating material modifying inner site outer surface porous activated carbon fabric (ACF) using urethane reactions. end, fluorinated polyurethane (F-PU) materials were synthesized perfluoroalkyl alcoho...

We synthesized the novel methacrylate monomer bearing an oxazolidone structure (M1) and performed radical polymerization of M1 by traditional procedures. The glass transition temperature (Tg) obtained polymer (P1) was a significantly high value compared to that poly(methyl methacrylate) typical poly(urethane methacrylate)s. copolymers monofunctional urethane derived from 2-hydroxyethyl phenyl i...

Hindered urea bonds are introduced as self-healing units in a polymer electrolyte for Li-metal batteries. Differently from standard commercial separators, the poly(urea-urethane) system works hundreds of cycles after several damage/healing steps.

In this study, we report the synthesis and characterisation of a thermogelling poly(carbonate urethane) system comprising poly(ethylene glycol) (PEG), poly(propylene glycol) (PPG) and poly(polytetrahydrofuran carbonate) (PTHF carbonate). The incorporation of PTHF carbonate allowed for the control of the lower critical solution temperature (LCST) and decreased critical gelation concentration (CG...

The worldwide production of polymeric foam materials is growing due to their advantageous properties light weight, high thermal insulation, good strength, resistance and rigidity. Society creates ever increasing amounts poly-urethane (PU) waste. A major part this waste can be recycled or recovered in order put into further use. PU industry committed assist play its the process. recycling recove...

This paper reports the hydrolytic degradation and protein release studies for a series of newly synthesized thermogelling tri-component multi-block poly(ether ester urethane)s consisting of poly[(R)-3-hydroxybutyrate] (PHB), poly(propylene glycol) (PPG), and poly(ethylene glycol) (PEG). The poly(PEG/PPG/PHB urethane) copolymer hydrogels were hydrolytically degraded in phosphate buffer at pH 7.4...

I read with special interest the meta-analysis of Blot et al. in a recent issue of Critical Care [1]. In a systematic review of the available literature of both laboratory and clinical studies, comparing the sealing efficacy of polyvinylchloride cuffed endotracheal tubes (PVC-ET) versus poly-urethane cuffed endotracheal tubes (PU-ET), they demonstrated a clear advantage with a demonstrated dela...

Polyurethane (PU) is a unique polymer that has versatile processing methods and mechanical properties upon the inclusion of selected additives. In this study, freestanding bio-based polyurethane film screen-printed electrode (SPE) was prepared by solution casting technique, using acetone as solvent. It one-pot synthesis between major reactants, namely, palm kernel oil-based polyol 4,4-methylene...

In this study, we demonstrate that vanillin is a valuable source of aromaticity can be explored for poly(hydroxy urethane) production with competitive properties, avoiding the use oil-based or hazardous precursors.
